Will musculoskeletal, visual and psychosocial stress change for visual display unit (VDU) operators when moving from a single-occupancy office to an office landscape?
This study investigated the effect of moving from single-occupancy offices to a landscape environment. Thirty-two visual display unit (VDU) operators reported no significant change in visual discomfort. Lighting conditions and glare reported subjectively showed no significant correlation with visual discomfort. Experience of pain was found to reduce subjectively rated work capacity during VDU tasks. The correlation between visual discomfort and reduced work capacity for single-occupancy offices was rs=.88 (p=.000) and for office landscape rs=.82 (p=.000). Eye blink rate during habitual VDU work was recorded for 12 operators randomly selected from the 32 participants in the office landscape. A marked drop in eye blink rate during VDU work was found compared to eye blink rate during easy conversation. There were no significant changes in pain intensity in the neck, shoulder, forearm, wrist/hand, back or headache (.24<or=p<or=.67). Pain levels in different body areas were significantly correlated with reduced work capacity, .77<rs<.99 (p=.000).
